The radius of the disk is R, and the mass of the disk is M. Using the parallel axis theorem and theequation for the moment of inertia of a disk about its central axis developed in the previous example, Eq. (8), the moment of inertia of the disk about the specified axis is Fig.
Short Circuits. Short circuits are the second most common reason for breaker tripping and are a more serious concern. Short circuits occur when the black hot wires inside your electrical service panel come in contact with either other hot wires or neutral wires.
Low battery voltage can also affect fuel delivery by causing the fuel pump to run slower than normal. This, in turn, causes, low fuel pressure and a lean fuel condition. Under some conditions, a low battery may even prevent one or more injectors from opening normally causing lean misfire and/or hard starting.
